[Prior Art] An electrical connector for connecting a conductor of a sub-circuit substrate to a conductor of a mother circuit substrate is disclosed in Japanese Laid-Open Patent Publication No. 2000-091032. The electrical connector has an insulating outer shouting for forming an elongated groove between the side walls to receive the sub-circuit substrate, the outer casing is opened along its elongated groove to form a terminal cavity, and the ejector (4) eet() is provided at the elongated groove=end. r) a groove, and having a female garment receiving hole connected to the groove; and having a plurality of ends mounted on the terminal cavity or having conductivity extending to the elongated groove and being fastened to the sub-circuit substrate a contact portion of the cymbal, and a tail end portion of the conductor extending from the outer casing and fastened to the female circuit board; further comprising a mounting member having a retaining portion for fastening the mounting member receiving hole of the outer casing, The buckle is fixed on the female circuit board to fix the connector to the fastening portion of the mother circuit substrate: and the ejector holding portion; the ejector of the body, the ejector ... M is the surface of the release surface The shaft in the top groove is mounted on the mounting part of the push-piece, and the ejector is rotated in a direction away from the elongated groove to push the quilt in the direction of the tribute Circuit board.曰本专利特平平〇9_〇〇7693 R — 接 I I, ～93 Figure 7 does not have an ejector mechanism for detaching the connected small circuit board from the connector for making a small gang The Thunder is used as a circuit board connected to the main circuit board and connected to the length of the outer casing of the insulating system, and the pin is supported by the L-shaped 92554.doc 1260830. When the rotation is performed, the operation portion of the lever is rotated outward, and the action portion that is fastened to the front end of the small-sized circuit board is moved upward to push the small-sized circuit board in the pull-out direction. This lever is engaged with a notch formed on the side of the small circuit board. A connector for a small electrical connection is disclosed in Japanese Laid-Open Patent Publication No. Hei 07-288154. The connector includes a button incorporating the outer casing of the small circuit board disposed at an end portion of the outer shunt in the longitudinal direction, and a crank that rotates in accordance with the above-described movement and pushes one end of the small circuit board out of the outer casing. Patent Document 3 discloses that the connector includes a locking portion that is formed in the body, and the locking portion is fastened to a side groove formed in a portion of the small circuit board to block the small circuit. The connector is detached from the above. Patent Document 3 further discloses a connector in which the 'upper housing has an elastic locking portion for fastening the other portion of the small-sized f-plate. The elastic locking portion is attached to one end of the small-sized circuit board. When the connector body is pushed out, the small circuit board is pressed and bent to release the buckle of the small circuit board. The electrical connector of Japanese Patent Laid-Open No. 2000-091032 prevents the sub-circuit substrate from being detached from the electrical connector. The upper end of the ejector is provided with a pressing portion placed at the upper edge of the sub-circuit base =. Therefore, the ejector is bulky' and the height of the electrical connector becomes high. And because the higher ejector will be sideways to the outside; the bottom side therefore requires space on the side of the electrical connector, which does not increase the mounting density of the electrical connector. The connector of the Japanese Patent Laid-Open No. 9_〇〇7693 is for preventing the small-sized circuit board from being detached from the connector. The protrusion at the lever is formed with a notch that is fastened to the small-sized circuit board. Therefore, the leverage is large, making the height of the connector high by 92554.doc 1260830. Further, since the lever of this height is tilted to the outside of the side, space is required on the side of the connector, and the mounting density of the electrical connector cannot be improved. The connector of Japanese Patent Laid-Open No. Hei 07-288 154 and the connector of Patent Document 2 also have a fastening portion and a resilient fastening portion that are fastened to the side grooves of the small circuit board, so that the orientation of the connector is increased. Further, since the locking portion is provided, the elastic locking portion is deformed to the side surface, so that the connector is enlarged on the side surface, and the mounting density of the electrical connector cannot be increased. SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object thereof is to prevent small-sized printing by embedding a flexible locking portion provided in a casing into a through hole of a small printed circuit board to be inserted. The circuit board makes it difficult for the small printed circuit board to be detached from the electrical connector, thereby lowering the height of the IH and making the electrical connection low, thereby miniaturizing and improving the mounting of the electrical connector into the above (four) 'the present invention The electrical connection port is characterized in that, when the depth direction, the width direction, and the thickness direction of the wood are orthogonal to each other, the j direction is observed by a shape extending from the depth direction and a shape extending in the width direction, and the system is A small printed circuit board having at least HgI1, STI Μ , , /, or a hole extending in or out of the thickness direction is formed between the walls of the finger 1 and extending in the thickness direction and in the depth direction ;- The second outer casing 1 is erected from the front side of the outer casing in the width direction of the outer casing, and is formed in the thickness direction with respect to the second wall. In the outer side of the width direction, the opening 92054.doc 1260830 is externally connected, and has a valley disposed on the first outer casing and led to the first outer casing, and is elastically deformable in the thickness direction. a contact portion; and an ejector, which is connected to be placed around the axis extending in the depth direction, and the # knife is located in the accommodating chamber as a push (four), and the front end I is connected to the side of the communication An operation portion; the structure is such that the guide groove receives the small end of the inserted person == both ends of the width direction, and the inner side edge of the depth direction is pushed up so that the contact portion of the contact member contacts the conductive portion, and the other is made by The part moves in the depth direction, so that the push-out part moves to the deep-production side: the front position is 'pushing' (four) pushes out the small printed circuit board and pulls out the first one: and has a lockable locking part, which is tied to the The first wall of the outer casing is inserted into the inner wall of at least one of the walls of the outer casing, and protrudes in the thickness direction to be inserted into the through hole of the inserted small printed circuit board. When the small printed circuit board is inserted into the electrical connector, the guide groove is inserted into both end edges of the printed circuit board in the visibility direction, and the inner edge in the depth direction is incorporated into the accommodating portion so that the contact portion of the contact member contacts the conductive portion. In this case, since the locking portion is bent and inserted into the through hole of the small printed circuit board to lock the small printed circuit board, the small printed circuit board is loosened by the self-electrical connector. In addition, since the number of contacts is large due to the number of poles, there is also a holding force of a small printed circuit board due to the contact force of the contacts. Therefore, it is difficult for the small printed circuit board to be disconnected from the electrical connector. Further, when the operation portion of the ejector is moved in the depth direction, the push J portion is moved to the front position ' in the depth direction, and the push-out portion pushes out the small printed circuit board and pulls it off. In this case, the locking portion may be bent due to its flexibility, 92554.doc 1260830 from the through hole of the type printed circuit board. The ejector is fixed in the depth direction of the small printed circuit board by the front edge or the edge of the width direction, so that the height of the ejector is lowered and the height of the electrical connector is reduced: miniaturization is achieved. In addition, since the space outside the width direction of the electrical connector does not need to be two large, the mounting density of the electrical connector is improved. Further, in the electrical connector of the present invention, at least one of the second wall facing the second wall opposite to the direction of the second direction and the second direction facing the second direction is locked. In such a manner, the M? direction is opposite to the locking portion to hold the small printed circuit board. Thus, the force of the small printed circuit board is increased, making it difficult for the small printed circuit board to be loosened from the electrical connector. Further, a locking portion in which a plurality of pairs oppose each other is provided in the thickness direction. With such a method, the locking portion is inserted into the through hole of the small printed circuit board, so that the force for holding the small printed circuit board is increased, making it difficult for the small printed circuit board to be loosened from the electrical connector. Further, a plurality of locking portions are provided separately in the width direction. According to this method, the locking portion is inserted into the through hole of the small printed circuit board, so that the force of the small printed circuit board is increased, making it difficult for the small printed circuit board to be loosened from the electrical connector. And the detent force is balanced in the direction of visibility, so it is difficult to make a small printed circuit board inclined from the thickness direction. Further, the locking portion is provided such that the cross-sectional front end of the surface facing the thickness direction becomes smaller. In this way, the outer surface of the locking portion is inclined toward the front end, so that the guiding function can be used in the through hole of 92554.doc 1260830.
